LTE/LTE-A utilizes OFDM (OFDMA) on the uplink, and utilizes single-carrier frequency division multiple access (SC-FDMA) on uplink.OFDMA carrier wave and/or SC-FDMA carrier wave can be divided into multiple (K) orthogonal sub-carriers, and this multiple orthogonal sub-carriers is also commonly called frequency modulation, frequently groove etc.Each subcarrier can modulate data.Spacing between adjacent sub-carriers can be fixing, and the total quantity of subcarrier (K) can depend on system bandwidth.Such as; for the corresponding system bandwidth (there is guard band) of 1.4,3,5,10,15 or 20 megahertzes (MHz); when having the sub-carrier separation of 15 KHz (KHz), K can equal 72,180,300,600,900 or 1200 respectively.System bandwidth can also be divided into some subbands.Such as, a subband can contain 1.08MHz, and can there is 1,2,4,8 or 16 subband.

FDD can be used to operate (such as, using paired frequency spectrum resource) for carrier wave or TDD operation (such as, using azygous frequency spectrum resource) sends two-way communication.The frame structure (such as, 1 type frame structure) of FDD and the frame structure (such as, 2 type frame structures) of TDD can be defined.The time interval can use basic time unit T _sthe multiple of=1/30720000 represents.Each frame structure can have radio frames length T _f=30720OT _s=10ms, and length can be comprised separately for 153600T _stwo fields of=5ms or time slot.It is 30720T that each field can comprise length _sfive subframes of=1ms.

LTE/LTE-A network support has many processes II type HARQ of the independent HARQ procedure of configurable number.Each HARQ procedure wait-receiving mode before transmission new data or transmission block confirms (ACK).LTE/LTE-A uses asynchronous HARQ transmission on the uplink, and uses synchronous HARQ to transmit on uplink.In both asynchronous HARQ and synchronous HARQ, ACK/NAK information can be provided in the some subframes after DL transmission or UL transmission.Usually, for LTE/LTE-AFDD carrier wave, in 4 subframes after transfer of data, send the ACK/NAK information being used for HARQ procedure.In asynchronous HARQ, the ACK/NACK through scheduling for subsequent transmission is not predetermined, and base station provides the instruction about sending which HARQ procedure in each subframe to UE.For the synchronous HARQ in FDD, in a predetermined quantity subframe of UE after receiving NAK, perform the second transmission of specific HARQ process.Usually, for LTE/LTE-AFDD carrier wave, occur in the subsequent UL transmissions of identical HARQ procedure 4 subframes after receiving NAK.For the synchronous HARQ in TDD, ACK/NAK information can be received transmitting in the subframe i be associated with the UL in subframe i-k, wherein, k can be defined according to TDDUL/DL configuration.For the NAK received in subframe n-k, the subsequent transmission of specific HARQ process can be performed in subframe n, wherein, k can be defined according to TDDUL/DL configuration.

Fig. 2 describes the frame structure 200 of TDD carrier wave.For tdd frame structure, each subframe 210 can carry UL or DL business, and special subframe (" S ") 215 can be used to be transferred to switching between UL transmission at DL.UL subframe and the distribution of DL subframe in radio frames can be symmetrical or asymmetric, and can by semi-static or dynamically reconfigure.Special subframe 215 can carry some DL and/or UL business, and can comprise protective time slot (GP) between DL business and UL business.Can by arranging timing advance to realize at UE to the switching of DL business from UL business, and without the need to using special subframe or the protective time slot between UL subframe and DL subframe.Can support to have the periodic TDD configuration of switching point of the half (such as, 5ms) equaling frame period (such as, 10ms) or frame period.Such as, tdd frame can comprise one or more special frames, and the period between special frames can determine TDDDL to the UL switching point periodicity for described frame.

For LTE/LTE-A, define seven different TDDUL/DL configurations, it provides the subframe of the DL between 40% and 90%, as shown in table 1.

Table 1:TDD configuration

Because some TDDUL/DL configuration has the UL subframe fewer than DL subframe, so few techniques can be used to send ACK/NAK information for the relation integration in the PUCCH transmission in uplink sub-frames.Such as, binding can be used to combine ACK/NAK information, to reduce the amount of the ACK/NAK information sent.If be ACK for the ACK/NAK information of each subframe of described relation integration, then described ACK/NAK information combination can be become to be set to the individual bit confirming (ACK) value by ACK/NAK binding.Such as, for specific sub-frame, ACK/NAK information can be the binary system ' 1 ' for representing ACK and the binary system ' 0 ' for representing Negative Acknowledgement (NACK).Can use and with operation, ACK/NAK information is bound to the logic of the ACK/NAK bit of relation integration.Binding reduces the amount of the information sent on PUCCH, and therefore increases the efficiency of HARQACK/NAK feedback.The multiplexing multiple bits sending ACK/NAK information in a uplink sub-frames can be used.Such as, Channel assignment can be utilized to use PUCCH format 1b to send nearly four bits of ACK/NAK.

Wireless communication system 100 can support the operation on multiple carrier wave, and it can be called as carrier aggregation (CA) or multi-carrier operation.Carrier wave can also be called as component carrier (CC), layer, channel etc.Term " carrier wave ", " layer ", " CC " and " channel " are used interchangeably in this article.Carrier wave for down link can be called as down link CC, and can be called as up link CC for the carrier wave of up link.UE115 can be configured with multiple down link CC and one or more up link CC to carry out carrier aggregation.Multilayer base station 105 can be configured on multiple CC, support the communication with UE on the downlink and/or uplink.Therefore, UE115 can receive data and control information from a multilayer base station 105 or from multiple base station 105 (such as, single or multiple lift base station) on one or more down link CC.Data and control information can be sent to one or more base station 105 by UE115 on one or more up link CC.Carrier aggregation can be used with regard to both FDD and TDD component carriers.For DL carrier aggregation, when multiple DL transmission occurs in a subframe, multiple bits of feeding back ACK/NAK.PUCCH format 3 can be used to send nearly 22 bits of ACK/NAK for DL carrier aggregation.

Fig. 3 shows the wireless communication system 300 of the employing carrier aggregation according to various embodiment.Wireless communication system 300 can illustrate some aspects of wireless communication system 100.Wireless communication system 300 can comprise one or more base station 105, and it uses one or more component carrier 325 (CC ₁-CC _n) communicate with UE115.Base station 105 can send information to UE115 on component carrier 325 on forward direction (down link) channel.In addition, UE115 can send information to base station 105-a on component carrier 325 on reverse (up link) channel.The various entity describing Fig. 3 and be associated with some embodiments in the disclosed embodiments other accompanying drawing time, for explanatory purposes, use the term that is associated with 3GPPLTE or LTE-A wireless network.But, will be appreciated that wireless communication system 300 can operate in other network, such as but not limited to OFDMA wireless network, cdma network, 3GPP2CDMA2000 network etc.Component carrier CC ₁-CC _none or more component carriers in 325 can be in same frequency operational frequency bands (in band) or be in different operating frequency band (interband), and in band, CC can be continuous or discontinuous in operational frequency bands.

Within the wireless communication system 300, UE115 can be configured with the multiple CC be associated with one or more base station 105.A CC is designated as the main CC (PCC) of UE115.Semi-statically PCC can be configured based on each UE by higher level (such as, RRC etc.).Some uplink control information (UCI) (such as, ACK/NAK, channel quality information (CQI), dispatch request (SR) etc.) is carried by PCC when sending on PUCCH.Therefore, ULSCC can be not used in the PUCCH of given UE.UE115 can be configured with asymmetric DL to ULCC and assign.In LTE/LTE-A, support that DL to the UL of nearly 5:1 maps.Therefore, for reaching 5 DLCC, a ULCC (such as, PCCUL) can carry UCI (such as, ACK/NAK) on PUCCH.

In the example shown in Fig. 3, UE115-a is configured with PCC325-a and SCC325-b be associated with base station 105-a and the SCC325-c be associated with base station 105-b.Wireless communication system 300 can be configured to the carrier aggregation supporting the various combinations using FDD and/or TDDCC325.Such as, some configurations of wireless communication system 300 can support the CA for FDDCC (such as, FDDPCC and one or more FDDSCC).Other configuration can support the CA using TDDCC (such as, TDDPCC and one or more TDDSCC).In some instances, the TDDSCC for CA has identical DL/UL and configures, and other example support has the TDDCA of the CC that different DL/UL configures.

In certain embodiments, wireless communication system 300 can support TDD-FDD joint operation, comprise the joint operation (the dual connectivity such as, when the base station 105 of the multiple CC configured for UE115 has the backhaul ability etc. of reduction) of CA and other type.The UE115 that TDD-FDD joint operation can make support FDD and TDDCA operate is used CA or is accessed both FDD and TDDCC with single CC pattern.In addition, traditional UE (such as, single mode UE, have the UE of FDDCA ability, have the UE etc. of TDDCA ability) with various ability can be connected to FDD or the TDD carrier wave of wireless communication system 300.

Usually, simplify carrier aggregation, the benefit simultaneously still obtaining carrier aggregation may be useful.Especially, when TDD component carrier (CC) is principal component carrier wave (PCC), support that FDD+TDD carrier aggregation presents significant challenge.These challenges may be due to the fact that when TDDCC is designated as PCC to carry PUCCH, and the set for the DL subframe (or UL subframe) of FDD carrier wave is the superset of the set of the DL subframe (or UL subframe) of TDD carrier wave.This fact may make such as HARQ timing design, scheduling timing and channel condition information (CSI) feedback etc. become complicated.Therefore, the method for simplifying being provided for FDD+TDD carrier aggregation may be useful, particularly when TDDCC is PCC.

If UE does not have full duplex ability, then may there is other problem because of FDD+TDD carrier aggregation.Such as, when FDD component carrier (CC) is designated as principal component carrier wave (PCC), the UE with full duplex ability may be needed.Like this, half-duplex UE is allowed can to increase the deployment of FDD+TDD carrier aggregation at FDDCC as the method realizing FDD+TDD carrier aggregation when PCC.

In various methods described in this article, FDD+TDD carrier aggregation can be realized to operate according to the TDDUL/DL configuration for TDD Operation Definition in table 1.But should be appreciated that described technology is applicable to other TDDUL/DL configuration, described other TDDUL/DL configures and should define for TDD operation.

In several embodiments, when supporting FDD+TDD carrier aggregation, the FDDCC for down link (FDDDL) and/or the FDDCC for up link (FDDUL) can be considered as TDDCC similarly in specific T DDUL/DL configuration.In other words, can determine with reference to sub-frame configuration for FDDCC.Described reference sub-frame configuration can be corresponding with available TDDUL:DL sub-frame configuration, and it can be identical or different for the uplink communication on FDD carrier wave and downlink communication.Then can according to determine on FDDCC, to perform communication on cordless communication network with reference to sub-frame configuration.

In certain embodiments, the reference sub-frame configuration of the DL carrier wave of FDDCC can be determined.In addition, the reference sub-frame configuration of the UL carrier wave of FDDCC can be determined.Under these circumstances, in both the downlink and in the uplink, direction respectively according to determined reference sub-frame configuration, FDDCC can perform the communication on cordless communication network.In one example in which, hybrid automatic repeat-request (HARQ) can be determined regularly based on reference to sub-frame configuration.HARQ timing can refer to such as physical down link sharing channel (PDSCH) transmission or the timing between physical uplink link shared channels (PUSCH) transmission and corresponding ACK/NAK message.In another example, scheduling timing can be determined based on reference to sub-frame configuration.Scheduling timing can refer to the timing between such as physical downlink control channel (PDCCH) or enhancement mode/evolved PDCCH (EPDCCH) and PDSCH or PUSCH.

Expect that various method processes the special subframe in the FDDDL being considered as TDDUL/DL sub-frame configuration similarly.In addition, expect that various method processes the special subframe in the FDDUL being considered as TDDUL/DL sub-frame configuration similarly.Also expect that various method utilizes in FDDDL, to be not useable for DL according to reference to sub-frame configuration and/or in FDDUL, to be not useable for the subframe of UL.Such as, such subframe may be used for scheduling.

Fig. 4 describes the example of one group of sub-frame configuration of an execution mode for method described herein.For this example, for clarity sake, a FDDCC and TDDCC is related to.As shown in the figure, TDDCC is confirmed as or is designated as PCC, and wherein FDDCC is SCC.1 (see table 1 above) can be configured according to TDDUL/DL and configure TDDPCC.

In certain embodiments, the reference sub-frame configuration of TDDUL/DL configuration 5 for FDDDL is determined.In this case, the subframe of percent in radio frames 90 may be used for DL Tong Xin – FDDDL is not useable for this UE PDSCH with reference to the subframe 2 in sub-frame configuration.But subframe 2 may may be used for other UE, and/or can by multimedia broadcast/multicast service (MBMS) for this UE or other UE.

In certain embodiments, TDDUL/DL configuration 0 is determined for the reference sub-frame configuration for FDDUL.In this case, the subframe 0 and 5 that in radio frames, the subframe of 60 percent can be used in this FDDUL reference sub-frame configuration of UL Tong Xin – is not useable for UL transmission, and subframe 1 and 6 is not useable for UL transmission at least partly.

Optionally or expectation can be looked, such as, based on suitable parameter, make the determination to the reference sub-frame configuration for FDDDL and/or UL by UE or by the base station of cordless communication network.Such as, the reference sub-frame configuration being used for FDDDL and/or UL can be picked as the configuration compatibility with TDDPCC.Compatibility can be with regard to identical HARQ two-way time (RTT), identical configuration etc.As another example, reference sub-frame configuration for FDDDL and/or UL can be selected to consider the maximum of the ACK/NAK bit on TDDPCC.As another example, reference sub-frame configuration for FDDDL and/or UL can be selected based on the ability of UE (such as, UE is the maximum quantity etc. of DLCC and/or ULCC that full duplex or semiduplex, its UE grade, UE can be polymerized).

In certain embodiments, can arrange (such as, hard coded) for UE with reference to sub-frame configuration, and the storage device or memory therefore such as by accessing UE is determined.In other embodiments, such as can be signaled to the some UE in described UE or described community with reference to sub-frame configuration by the base station of service specific cell especially, or be signaled to described serving BS from described UE.

In certain embodiments, the reference sub-frame configuration for FDDDL and FDDUL can be identical.In other embodiments, different reference sub-frame configuration can be determined for FDDDL and FDDUL respectively.As mentioned above, possible reference sub-frame configuration can be restricted to the existing seven kinds of configurations shown in table 1.But the expansion that the TDDUL/DL for TDD exceeding current configuration configures also is possible.

In example in the diagram, the reference sub-frame configuration for FDDDL has the special subframe for subframe 1 and subframe 6.Expection several methods processes the special subframe in FDDDL.

A kind of method is that such special subframe is considered as conventional DL subframe.When such method is used for the exemplified period of the day from 11 p.m. to 1 a.m, DL transmission can for full duplex UE across whole subframe.On the other hand, for half-duplex UE, if corresponding PCC subframe is special subframe, then for DL transmission, special subframe can be ignored.For shown example, subframe 1 and 6 will be ignored, this is because the subframe 1 and 6 in the sub-frame configuration of PCC is special subframes for DL transmission.

Another kind method is that the corresponding sub-frame configuration of Based PC C is to process the special subframe in FDDDL.When such an approach is used, although do not illustrate in the example in fig. 4, if the corresponding subframe in the TDDUL/DL configuration of PCC is DL subframe, then conventional DL subframe can be regarded as the special subframe in the reference sub-frame configuration of FDDDL.As shown in the example, special subframe can be regarded as the special subframe 1 and 6 in the reference sub-frame configuration of FDDDL, this is because the corresponding subframe 1 and 6 in the TDDUL/DL configuration of PCC is special subframes.Optionally or depending on expectation the such special subframe in FDDDL can be set to the configuration of a certain special subframe (such as; as in normal cyclic prefix (CP), 12 down link pilot timeslot (DwPTS) symbols, 1 protective time slot (GP) symbol and 1 uplink pilot time slot (UpPTS) symbol).For full duplex UE, this method may be preferred.Or, the such special subframe in FDDDL can be set to the special subframe identical with the sub-frame configuration of corresponding PCC special subframe and configure.For half-duplex UE, this alternative method may be preferred.

In example in the diagram, the reference sub-frame configuration for FDDUL also has the special subframe for subframe 1 and subframe 6.In addition, expect that several methods processes the special subframe in FDDUL.

Method is that such special subframe is considered as a conventional DL subframe, is not useable for UL and sends.When such method is used for the exemplified period of the day from 11 p.m. to 1 a.m, UL sends can be limited to subframe 2-4 and subframe 7-9, and sends for UL, can ignore for the special subframe 1 and 6 in the reference sub-frame configuration of FDDUL.

Another kind method is that the corresponding sub-frame configuration of Based PC C is to process the special subframe in FDDUL.When such an approach is used, although do not illustrate in the example in fig. 4, if the corresponding subframe in the sub-frame configuration of PCC is DL subframe, then conventional DL subframe can be regarded as the special subframe in the reference sub-frame configuration of FDDUL.As shown in the example, special subframe can be regarded as the special subframe 1 and 6 in the reference sub-frame configuration of FDDDL, this is because the corresponding subframe 1 and 6 in the sub-frame configuration of PCC is special subframes.Optionally or expectation can be looked, the such special subframe in FDDDL is set to a certain special subframe configuration (such as, 2 UpPTS symbols).For full duplex UE, such method may be preferred.Or, the such special subframe in FDDUL can be set to the special subframe identical with the sub-frame configuration of corresponding PCC special subframe and configure.For half-duplex UE, this alternative method may be preferred.

Another method is that the special subframe in FDDUL is considered as special subframe, and such special subframe is set to a certain special subframe configuration (such as, 2 UpPTS symbols), and the type of subframe in the sub-frame configuration of no matter PCC.Therefore, in such method, the type of corresponding subframe in the TDDUL/DL configuration of PCC will not affect or determine the process to the special subframe in FDDUL.This method may be more suitable for full duplex UE.

Preceding method (such as, having the determination to the reference sub-frame configuration for FDDCC, FCCDL and/or FCCUL) can allow to use existing carrier aggregation to design.Such as, it is compatible that such method and existing version 10 and version 11 carrier aggregation design.Therefore, can reduce and/or avoid may the potential challenge occurred because being designed for the new departure supporting FDD+TDDCA (with the joint operation of other type).Such as, be used for FDDCC with reference to sub-frame configuration can allow TDD+TDDCAHARQ timing design (such as, version 11TDD+TDDCA etc.) for TDD+FDDCA.

Latent defect FDDCC (such as, FDDDL and/or UL) being considered as reference sub-frame configuration is all DL and UL subframes that not can utilize completely in FDDCC.In other words, according to reference to sub-frame configuration, when realizing such method, some subframes in some subframes in FDDDL subframe and/or described FDDUL subframe may be unavailable.As discussed above, this is the situation for the subframe 2 in the FDDDL shown in Fig. 4 and the subframe in FDDUL 0,1,5 and 6.

A kind of method of the utilance for improving such subframe allows the scheduling in such subframe.In other words, FDDDL can be regarded as a kind of with reference to sub-frame configuration, and FDDUL can be regarded as another kind of with reference to sub-frame configuration (such as, same reference configuration or different reference configuration), allow the scheduling be not useable in addition in the subframe of corresponding DL/UL reception/transmission simultaneously.

For subframe (such as, the subframe 2 in the example of Fig. 4) such in FDDDL, PDSCH can be dispatched.When TDDCC does not exist across carrier dispatching for FDDCC, PDSCH can be dispatched by the one or more control channels in the identical subframe of identical FDDCC or another FDDCC in such subframe.In the example shown, control channel (such as, PDCCH/EPDCCH) can be provided in the subframe 2 of FDDDL, to dispatch PDSCH in the subframe 2 of FDDDL.Optionally or look expectation, can in such subframe semipermanent scheduling PDSCH.When TDDCC exists across carrier dispatching for FDDCC, can enable across subframe scheduling for such subframe.Such as, the one or more control channels in the subframe 1 of TDDCC can dispatch PDSCH in such subframe.

Ack/nack (ACK/NAK) can be provided to feed back for the such subframe (uplink sub-frames in the reference sub-frame configuration of such as, FDDDL) for dispatching.ACK/NAK feedback can bind the ACK/NAK feedback of other downlink subframe one or more in the reference sub-frame configuration of FDDDL.Such as, the ACK/NAK of the FDDDL subframe 2 in Fig. 4 can bind the ACK/NAK of FDDDL subframe 1 in the time domain.

For the such subframe (such as, the subframe 0,1,5 and 6 in the example of Fig. 4) in FDDUL, PUSCH can be dispatched.When TDDCC does not exist across carrier dispatching for FDDCC, PUSCH can be dispatched by the one or more control channels in the subframe of identical FDDCC or another FDDCC in such subframe.In the example shown, control channel (such as, PUCCH/EPUCCH) can be provided in the subframe 2 of FDDUL, to dispatch PUSCH in the subframe 6 of FDDUL.Optionally or look expectation, can in such subframe semipermanent scheduling PUSCH.When TDDCC exists across carrier dispatching for FDDCC, can enable for such subframe across subframe scheduling (such as, for PUCCH/EPUCCH) or across subframe HARQACK (such as, for PHICH).Such as, the one or more control channels in the subframe 1 of TDDCC can dispatch PUSCH in the subframe 6 of FDDUL.Or such scheduling can via FDD component carrier.If undesirably across subframe HARQ (such as, the PHICH resource pond of binding via ACK/NAK or increasing), then it may be suitable for not supporting that non-self-adapting UL retransmits via PHICH for such subframe.

Another latent defect is may there is restriction about being polymerized how many CC in for the carrier aggregation of UE.This can be such as when TDDCC is PCC and FDDCC is SCC, and situation when relating to No. 5 TDD sub-frame configuration (such as, as the sub-frame configuration of TDDCC or the reference TDD sub-frame configuration as FDDCC).This may be the DL:UL ratio because of No. 5 TDD sub-frame configuration with nine to one (9:1).Therefore, even if having the binding of ACK/NAK space, for specific CC, still may there are nearly nine (9) individual ACK/NAK bits will be fed back by UE.Because the PUCCH format 3 for ACK/NAK may have limited capacity (such as, 22 (22) individual bits are reached in version 11), therefore can support nearly two (2) the individual CC with No. 5 TDD sub-frame configuration (actual or reference).

This latent defect can be solved by the other binding of ACK/NAK.Alternatively or additionally, can such as by adopting two PUCCH format 3 to transmit in the subframe of CC by UE or supporting that parallel PUCCH transmits by two or more CC of employing (PUCCH format 3 transmission such as, on FDDCC and another PUCCH format 3 on TDDCC are transmitted).

Can be avoid use No. 5 TDD sub-frame configuration as the reference sub-frame configuration of FDDCC for solving the another replacement scheme of this latent defect.This can help to be polymerized more CC in for the carrier aggregation of UE.Such as, for both DL throughput and UL throughput, the polymerization separately with two (2) individual CC of No. 5 TDD sub-frame configuration (actual or reference) usually may than the polymerization more poor efficiency of five (5) individual CC separately with No. 2 TDD sub-frame configuration (actual or reference).In the first polymerization, ten eight (18) individual DL subframes and two (2) individual UL subframes are had to can be used for described UE.In the second polymerization, 40 (40) individual DL subframes and ten (10) individual UL subframes are had to can be used for described UE.

As mentioned above, if UE does not have full duplex ability, then may go wrong because of FDD+TDD carrier aggregation.Therefore, support that for FDD+TDD carrier aggregation the method for half-duplex UE may be needs, particularly when FDDCC is PCC.Under these circumstances, a kind ofly support that the method for half-duplex UE can be pass through scheduling decision.Such as, half-duplex UE can determine whether monitoring DL or send UL based on existing sending/receiving condition.Such as, if UE is configured in a periodic fashion (such as, periodically CSI, SRS, SR etc.) send uplink signal, then corresponding UL subframe can be considered as uplink sub-frames by described UE.For other subframe, whether described UE dynamic monitoring exists the DL transmission pointing to described UE.If exist DL transmission and described DL transmit based on HARQ timing need HARQ feedback, then the corresponding UL subframe for HARQ feedback also can be considered as UL subframe by described UE.

Other method can be the reference sub-frame configuration initiatively determined being used for FDDCC by half-duplex UE.Such determination can be made via explicit signaling (such as, clean culture or broadcast) or via conceal signaling (such as, deriving).

The explicit signaling going to half-duplex UE can relate to the specific reference sub-frame configuration indicating and will use.Such as, can send to a half-duplex UE (or multiple half-duplex UE) the reference sub-frame configuration be used to indicate for FDDCC is the signal that TDDUL/DL configures 1, thus is provided for six (6) the individual DL subframes of FDDDL and four (4) the individual UL subframes for FDDUL.

The conceal signaling going to half-duplex UE can relate to the described half-duplex UE of instruction and use the TDDUL/DL configuration of the TDDCC of its CC as reference sub-frame configuration.Such as, the signal of the TDDUL/DL configuration of the TDDCC be used to indicate using its CC can be sent to a half-duplex UE (or multiple half-duplex UE).Reference the sub-frame configuration that then UE of TDDCC had for TDDUL/DL configuration 2 can determine its FDDCC is that TDDUL/DL configures 2, thus is provided for eight (8) the individual DL subframes of FDDDL and two (2) the individual UL subframes for FDDUL.

If half-duplex UE has multiple TDDCC in its carrier aggregation, then such implicit expression is determined to depend on other parameter one or more.Such as, a certain wireless heterogeneous networks (RRC) configuration can indicate the reference sub-frame configuration of the FDDCC of described half-duplex UE to be that it has the TDDUL/DL configuration of the TDDCC of minimum community ID.
